Chuck Maddox’s Watch Blog

This page is a journal of my journey in the field of Horology, which is timekeeping. In other words, watch collecting. Which in my case is the collecting of chronograph watches. To contact me, email me at: .

Eberhardt & Co. also goofs on their bezel's like Tissot!

One of the things that's always pleasant about having a blog is hearing from people all over the world. A couple of days ago, I heard from Armando Camacho out of Guadalajara, Mexico in response to my recent blog post on the Tissot NASCAR Chronograph:


Have you noticed that Eberhard's Tazio Nuvolari chronograph has suffered the same malady for years (an absurd tachymeter scale with its numbers translated into MPH)?

Indeed I hadn'tand Eberhardt & Co.'s website has to be the singularly most difficult website I have ever tried to access. So when I replied to Armando, I also CCed Pascal Stratsma as Pascal has a couple of Eberhardt chronographs. Their replies were a near dead heat with pictures of two separate Eberhardt models which have the same screwy needless tachymetre conversion as the Tissot I had posted earlier. Here's Armando's provided photo first:

and this is the clearer of the two... The nice thing about this goof, is that at least one has the correct Tachy bezel underneath the crystal on the dial.

However the exact same thing is happening on this model that Pascal submitted to me:

What can I say... stupidity isn't limited to Tissot it'd seem!

Thanks to both Armando and Pascal for their contributions to this entry. I couldn't have done it without you!

Technically, the bezel (tachymetre) isn't incorrect. It is correct if you are reading miles over a given kilometer. Someone probably wanted to make something U.S.-specific and MPH specific and in doing so, over thought the entire thing. Errors do happen, but at the end of the day, no one does it better than the Swiss...

This is unbelievable. How difficult is it to take a look at the speedmaster dial and copy it :-)

What's the fuss- there's nothing wrong with these calibrations. All that two fixed relation tachymetres of this sort can do is tell you how many kmph vs mph you are going when you pass a KILOMETER marker (the Swiss have km markers at roadside). A US version could have been produced with the opposite conversion, but no fixed pair of tachymeters can do both! Anyway the calibration on the dial ("kilometers") will be accurate for any unit of measurement. For example if you travel between two roadside markers in 30 seconds you are going 60 units per hour and it doesn't matter if the units are inches, feet, yards, meters, kilometers or miles.

Sorry- a typo in the last blog. Should read "For example if you travel between two roadside markers in 60 seconds you are going 60 units per hour and it doesn't matter if the units are inches, feet, yards, meters, kilometers or miles."

Anyone experienced with using a tachymetric scale should know that it can also be used to measure hourly rate and heart beat.

For example, if a printer takes 60 seconds to output a sheet, the tachymetric scale will rightly show that the printer outputs 60 sheets per hour. If it takes 30 seconds for a sheet (twice as fast), the tachymetric scale will indicate 120 (twice as much), and so on...

On a base of 60 heart beats, if a heart beats 60 times in one minute, the tachymetric scale will show 60bpm. If it beats 60 times in 30 seconds (twice as less), the scale will show 120pbm (twice as more), and so on...

So for the record: indicating Miles IS a gross mistake. That only happens when someone who has never used a Tachymeter tries to implement it to make a watch look cooler. The tachymetric scale has been designed as a GENERIC scale, units-unrelated.
